[PATCH v3 00/12] pwm: add support for atomic update

Show all headers | View raw

Hello,

This series adds support for atomic PWM update, or IOW, the capability
to update all the parameters of a PWM device (enabled/disabled, period,
duty and polarity) in one go.

Best Regards,

Boris

Changes since v2:
- rebased on top of 4.3-rc2
- reintroduced pwm-regulator patches

Changes since v1:
- dropped applied patches
- squashed Heiko's fixes into the rockchip driver changes
- made a few cosmetic changes
- added kerneldoc comments
- added Heiko's patch to display more information in debugfs
- dropped pwm-regulator patches (should be submitted separately)

Boris Brezillon (11):
  pwm: introduce default period and polarity concepts
  pwm: define a new pwm_state struct
  pwm: move the enabled/disabled info to pwm_state struct
  backlight: pwm_bl: remove useless call to pwm_set_period
  pwm: declare a default PWM state
  pwm: add the PWM initial state retrieval infra
  pwm: add the core infrastructure to allow atomic update
  pwm: rockchip: add initial state retrieval
  pwm: rockchip: add support for atomic update
  regulator: pwm: implement ->enable(), ->disable() and ->is_enabled
    methods
  regulator: pwm: properly initialize the ->state field

Heiko Stübner (1):
  pwm: add information about polarity, duty cycle and period to debugfs
